PROBLEM TO BE SOLVED: To realize a light emitting diode-aligned light source of high illuminance by a method wherein it is enhanced in light availability. SOLUTION: A light emitting diode-aligned light source is equipped with a printed wiring board 11, light emitting diode chips 12 arranged in a line at prescribed spots on a conduction circuit, a pair of white resin pieces 14 formed on both the sides of the diode chips 12 in parallel with them, and a transparent resin piece 15 which seals up the diode chips 12 arranged in a line between the white resin pieces 14. Light emitted from the light emitting diode chips 12 is reflected by the white resin piece 14 and concentrated the light axis of the light source, whereby the light source is enhanced in light utilization efficiency and illuminance. |
